MANY people are now financing cars despite having the cash available.
If it appreciates, buy it - if it depreciates, lease it!
If I paid £50k for the car cash, I can't use that £50k to make more money elsewhere in appreciating investments.
As interest rates are so low, what I pay in interest I easily make more than that using the free cash I didn't tie up in the car.
It works best on new cars as PCP allows you to only pay for the depreciation part of the car, plus they offer much better rates to incentivise a new car over a used car buy.
